MF as Pretreatment of RO for Tertiary Treatment of Biologically Treated Distillery Spentwash
P. Sharma and H. Joshi
Abstract—Biologically treated spentwash from distillery
usually contains high chemical oxygen demand (COD),
biological oxygen demand (BOD), color, total dissolved solids
(TDS) and other contaminants. In India, reverse osmosis (RO)
treatment plants have been installed in many of the distilleries at
tertiary treatment, but are not properly working due to fouling
problem. To make the membrane process proven and reliable
technology, proper pre-treatment is mandatory which not only
improve quality of RO permeate but also increase life of RO. In
the present study, use of micro-filtration (MF) for pre-treatment
of RO has been evaluated at the tertiary treatment stage.
Experiments were optimized in terms of different operating
parameters viz. initial pH (pHo: 2–10), trans-membrane
pressure (1-5 bars) and temperature (15- 43°C). Experimental
data revealed that the MF could be an effective pre-treatment in
removing the pollutants (COD, color and TOC) and improving
performance and water recovery (permeate flux) in comparison
to RO alone. Removal efficiency for COD, color, TDS and TOC
was observed as 31.5%, 42.7% and 27.6% with MF,
respectively at optimized conditions with increased permeate
flux from 17.5 LPH (RO) to 32 LPH (MF-RO).
